Arduino IDE port

I tried to enter a simple sketch on the Arduino using Ardeuino IDE that comes with linaro 1.2 or 11.10 that comes with current OS download. I got the following error.
Arduino: 0154 (Linux), Board: "Arduino Due (Programming Port)"

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

When I tried to use IDE Tools > port, it was greyed out.
The website http://www.elinux.org/UDOO_programming_ ... controller says
"The Arduino IDE for UDOO comes already configured to see the Arduino DUE embedded programming port on the internal serial (/dev/ttymxc3) so is ready to use." but the port is not there.
I am connected via ethernet. Should I connect via usb?
Anyplace I can find help would be appreciated.

 

I'm also having this same problem (see attachment). No ports are available to choose from (greyed out), but the selected board is the DUE with the programming port. Is this an issue with the image? I'm using Linaro 11.10.

Any help would be greatly appreciated...

 

there has been a few threads on this, try these
viewtopic.php?f=8&t=99
viewtopic.php?f=6&t=141

I do believe this is the same issue

 

Yes, just found one of them. Thanks for the help, though!!

It'd be nice if this information was added to the manual (I didn't see it in there...). This is kind of crucial info to start using the Arduino side...
